Abstract (en)
[origin: EP3202840A1] The rubber composition of the present invention is prepared by mixing a rubber component (A), zinc oxide (B), and a co-condensate (C) having a softening point of 150°C or lower and containing a p-tert-butylphenol-derived constituent unit represented by the following formula (1), an o-phenylphenol-derived constituent unit represented by the following formula (2) and a resorcinol-derived constituent unit represented by the following formula (3), wherein the nitrogen adsorption specific surface area (N 2 SA) of the zinc oxide (B) measured according to the BET method is 6 m 2 /g or more and 110 m 2 /g or less, the mixing amount of the zinc oxide (B) is 5 parts by mass or more and 13 parts by mass or less based on 100 parts by mass of the rubber component (A), and the mixing amount of the co-condensate (C) is 0.1 parts by mass or more and 10 parts by mass or less based on 100 parts by mass of the rubber component (A). The co-condensate (C) is usable as a replacement for p-tert-octylphenol and p-nonylphenol, has a softening point lower than the maximum temperature in a rubber processing step, and has excellent dispersibility in rubber.
